Some guys are very sexy with or without hair on their heads, this is what I've noticed. Like Christopher Meloni and Derek Jeter to name a few. It's all about their self confident that make them attractive to others.
Lately, a few guys that sucked me off were bald, eventhough they're in late 30s or early 40s. This may have something related to their heredity. When I first met them, on separate occasions, they'd baseball caps on, both were good looking and hot as fuck, in fact, one resembled of the younger Derek Jeter.
